door senser + texting/emails?

[VinylxScratches]

Anyone know if this is possible? I would like to set door sensors when it opens, I get texted or emailed? I am beginning to research into it. My alternative is webcam of some sorts but I have two doors that I'd like to watch... Any ideas?

Is there any programmable sensors out there that would work in .NET?

There are plenty of on/off switches which could be used to accomplish this - almost any position sensor (optical interrupter, capacitive sensor would probably be the easiest here). You would need to tie the sensor to an I/O port of your computer for power and voltage measurements. This could be done using either direct cabling or using a wireless microcontroller. The programming bit should be pretty straightforward using an event-driven approach, where the e-mail event is triggered when the voltage rises above/falls below a certain threshold value. This would be harder on the hardware end than Oyster's motion control algorithm, but the programming should be almost trivial.

There are also commercially available door sensors (googling "door sensor" yielded lots of options, e.g. Example), but what fun is that? 😛

Just a quick search turns up some interesting results for "arduino door sensor."

VitaminD was featured a few times.. Costs to run multiple cameras, but people seem to like it. Could point to other sources as well.

you could easily run some wire and have a little rig that allows a complete circuit when the door is closed. have it connected to a microcontroller.

SNMP Door anyone?

there are a ton of ways to do this...most security systems and pass card systems can monitor door activity. Many tie into SMTP readily.

The easiest way would probably be with a simple camera that sets events based on movement (the door in this case). They usually have mailing capability in their software already.
